Matt Parker @mattparker.dev · 01/01/2026Additionally, SharpDbg returns PresentationHints from the Debug Adapter Protocol, to indicate more info about variables, such as to identify pseudo variables, array elements, or a failed evaluation. Happy new year! 🎉 030

Matt Parker @mattparker.dev · 12/11/2025It was a goal of mine to be very conscious of performance, and run everything in memory where possible (avoid IPC overhead) - which it currently does, apart from MSBuild, which makes sense since its current multi threading model is a new process per “thread” 020
Matt Parker @mattparker.dev · 12/11/2025I had a lot of fun learning about Roslyn and Razor along the way! In terms of other IDEs, VS is not cross platform (and .NET Framework), VS Code is electron as well as not really comparable to a proper ide, and Rider, while powerful (and what I use daily) is very heavy. .. 120
Matt Parker @mattparker.dev · 12/11/2025At first, it was woeful performance of other IDEs in a very poorly specced AVD. I wanted to make something lightweight that would start fast, open a solution, build, and run projects. It kind of just went from there! E.g. I wonder how hard syntax highlighting would be to add, completions etc. .. 120
Matt Parker @mattparker.dev · 12/11/2025I’ve used Godot a little before in a 3D game, so I was familiar with the tooling which helped, and there was at least one built in Control node that I wish existed, but largely it was very mature and straightforward! Godot also had a CodeEdit node which meant I didn’t need to hand roll a lot of that 110
